but you do not want anything to do with 360 lobes

here's some specs at .004

278/282 197/199 410/411 111LC 2896283 Wolverine CS 4115 and the amount of lift you get with that duration, really long ramps
I threw it into the list so you can see where it fits along with the DC 260

All these cams may be too big (except the Jones) all are at .004 for those doing DCR calcs In duration order
A spread of 20 degrees advertised in the 214-224 range
note how the white box cams come in 276, 280 and 288 flavors for 214-224 cams (copycats)

“largest stock engine cam works best with 9:1 and gears 1,500-5200”


Not attempting to derail here, but I learned something interesting and got to apply it tonight. I now have a whole different opinion of the lowly 360 cam if it's used for the right application. We took a 1993 5.2 magnum and installed a 1988 roller cam out of a 360 and got .437/.455 lift with the 1.6 rockers, and picked up a little extra exhaust duration. This also put us from a 113 LSA to a 109, and then we put a chinese airgap with a 600 edelbrock. This is a very happy combination in a W100 with an HD 4 speed and 3.21 gears rolling on 31/10.50-15's, even with a set of 1968 318 truck manifolds dumping into 2-1/2 inch duals. Whole different animal than the roller cam 302 head 318 that it replaced.
